Conjunction (grammar) In grammar, a conjunction (abbreviated CONJ or CNJ) is a part of speech that connects words, phrases, or clauses, which are called its conjuncts. That description is vague enough to overlap with those of other parts of speech because what constitutes a "conjunction" must be defined for each language.
Logical conjunction. In logic, mathematics and linguistics, and ( ) is the truth-functional operator of conjunction or logical conjunction. The logical connective of this operator is typically represented as [1] or or (prefix) or or [2] in which is the most modern and widely used. The and of a set of operands is true if and only if all of its ...
A conjunctive grammar is defined by the 4- tuple where. is called a nonterminal symbol or a variable. Each variable represents a different type of phrase or clause in the sentence. Variables are also sometimes called syntactic categories. Σ is a finite set of terminal s, disjoint from V, which make up the actual content of the sentence. The ...
Conjunctive normal form. In Boolean logic, a formula is in conjunctive normal form (CNF) or clausal normal form if it is a conjunction of one or more clauses, where a clause is a disjunction of literals; otherwise put, it is a product of sums or an AND of ORs. As a canonical normal form, it is useful in automated theorem proving and circuit theory.
A conjunct is an adverbial that adds information to the sentence that is not considered part of the propositional content (or at least not essential) but which connects the sentence with previous parts of the discourse. Rare as it may be, conjuncts may also connect to the following parts of the discourse. It was raining.
In grammar, a part of speech or part-of-speech (abbreviated as POS or PoS, also known as word class[ 1 ] or grammatical category[ 2 ]) is a category of words (or, more generally, of lexical items) that have similar grammatical properties. Words that are assigned to the same part of speech generally display similar syntactic behavior (they play ...
Conjunctive adverb. A conjunctive adverb, adverbial conjunction, or subordinating adverb is an adverb that connects two clauses by converting the clause it introduces into an adverbial modifier of the verb in the main clause. For example, in "I told him; thus, he knows" and "I told him. Thus, he knows", thus is a conjunctive adverb.
Commutativity of conjunction. In propositional logic, the commutativity of conjunction is a valid argument form and truth-functional tautology. It is considered to be a law of classical logic. It is the principle that the conjuncts of a logical conjunction may switch places with each other, while preserving the truth-value of the resulting ...
